Brownie Dues Bingo

Materials needed:
Poster with cards for each girl drawn on it (like the example above).
Stickers that are small enough to fit into your boxes.

Each time a girl pays her dues she gets to place a sticker on a lettered square.  When she bingos, she gets a special treat (we keep a treasure bag filled with things from the dollar store).  A year's worth of dues will equal approximately three bingos.
